Full description


If you’re looking for an ultra-modern tactical and modular Airsoft sniper to turn into the ultimate sniper platform, then look no further than Ares’s MS 338. This spring powered bolt action Airsoft sniper rifle is filled to the brim with modular and tactical features and functions. Inspired by the MSR modular sniper rifle, the Airsoft MS 338 features flawless external construction, with the whole upper receiver / handguard and outer barrel being precision CNC machined from alloy. The barrel is a lightweight fluted design, where excess external material has been carefully machined out, reducing weight and increasing the barrel’s external rigidity. The flash hider is removable, by attaching a thread adaptor user can mount Airsoft suppressors to the MS 338.  

With five sections of 20mm RIS rail on the rifle and a further three short sections on the stock, the MS 338 has more than ample space for weapon accessories. A wide range of Airsoft scopes and optics can be mounted along the full-length, single piece upper handguard / receiver rail. The rail sections on the handguard’s lower and side surfaces are removable and can be re-positioned along the handguard as you require, allowing you to mount all the tactical accessories you need, like bipods, foregrips and flashlights, in positions that are practical for you to use.

The stock is a fully adjustable ergonomic design, intended to allow users to set the MS 338 up to be comfortable and practical to use. The butt plate can be extended via an easy-to-grip adjustment dial, to improve the weapon’s length of pull, and similarly the cheek rest is height adjustable, allowing users to adjust their eye-relief. All of this can be done in the field without the use of tools. To assist in storage and transportation, the stock is a side-folding design, reducing overall length by 25cm.

The bolt of the MS 338 is without question one of the best designed and manufactured Airsoft bolts. The bolt pull is both short and light, reducing how much energy and movement you need to put in to operate it, whilst the bolt-action itself is smooth and extremely easy to cycle. You can even operate it with your little finger!

Ideally suited for experienced Airsoft snipers, the MS 338 is an excellent investment, that combines precision manufacturing with great performance, that you can greatly enhance. With a little care and attention, you can take this excellently performing bolt action sniper right up to the magic 450-500 FPS mark.

Special Instructions

You will need to load your magazine fully and insert into the gun, then fill the magazine again before firing your first shot. The reason for this is the gun uses a BB feed internally to the hop unit that has to be full of BBs to consistently feed. Please note this weapon comes broken down into the top Assembly, the Stock, and front Hand guard. Should you need help feel free to call us on: 01484 644709.
